If you're experiencing a current issue, please start a new post with:

If I have GPU performance checked, and the problem occurs, I can exit InDesign and start InDesign again; this stops it temporarily, but after a while the problem comes back. To emphasize: this never occurs in the main text box on a page, only in one of the sidebar subsidiary text boxes on a page.
- Your InDesign version: 2026 (21.0 x64) but happened with a least the previous version, maybe one or two versions prior to that
- Operating system + version: Windows 11
- Hardware details (GPU, monitor setup, etc.):
- 12th Gen Intel(R) Core(TM) i9-12900 (2.40 GHz)
- 128 GB (128 GB usable)
- Windows 11 Pro 25H2 26200.7171
- NVIDIA GeForce RTX 3050. 8 GB
- Screenshots if possible: see above
Thanks for any help. This is really slowing down my work on this textbook.
